Acceptance certificate or delivery note cannot be completed
We identify the contract performance stage at which the document stopped being accepted and the product data already entered.
Advice for suppliers
KZTIN / NTIN / NKT for public procurement acceptance certificates
We help assess situations where a product cannot be found in the National Product Catalog, the system requires KZTIN or NTIN, a TRU code does not match a product record, or a delivery note, acceptance certificate or contract cannot be prepared.
When support is needed
We identify the exact scenario first
Client inquiries use variants such as KZTIN, КЗТИН, NTIN, НТИН, NKT and 'National Product Catalog.' What matters for the review is not the spelling, but the product, document and exact system message.
Product not found in NKT
We check the search query, category, characteristics and existing records in the National Product Catalog.
The system requires KZTIN / NTIN
We compare existing codes with the product and the document the supplier is preparing.
TRU code issue
We check the procurement's TRU or OKTRU code against the specification, product record and error text.
A product record is needed
We gather the name, intended use, model, manufacturer, unit of measurement and key characteristics.
A support request is needed
We prepare a focused inquiry for the system operator, buyer or technical support without unnecessary personal data.
What we do
Reviewing codes, records and next steps
The consultation provides a clear next step and a list of data to correct, supplement or send to the responsible participant in the process.
KZTIN / NTIN code selection
We assess the product's intended use and characteristics, existing codes and their connection to the specification. We do not substitute a random similar code.
NKT review
We check search results, categories, product attributes and the status of an existing record.
Error analysis
We compare the exact error text with the document preparation stage, contract and product data.
Product record
We help structure the description and list the characteristics that need supporting evidence.
Inquiry text
We explain exactly what is not working, which actions have been taken and what outcome is needed.
Action plan
We define the sequence of checks and inquiries. Registration and data acceptance decisions remain with the relevant system and organizations.
